Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The manifest has no lifecycle hook, and the agent-directory reference in the inspected runtime is used to construct local scan paths. However, bounded analysis of the CLI executable reveals credential-gathering code without resolving its reachability or destination, and the native addon is unsupported by the available analysis; this behavior remains unresolved. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-20T01:43:33.125Z - **Finished:** 2026-10-20T01:44:20.150Z - **Download time:** 5133 ms - **Static scan time:** 584 ms - **AI review time:** 41307 ms - **Total time:** 47025 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack is confirmed from the inspected JavaScript. The bundled executable contains a bounded source fragment that gathers provider credentials, but its activation and destination cannot be established from the available analysis. - **Trigger:** Running the bundled CLI could activate the unresolved native behavior; the extracted helper's caller is not established. - **Impact:** Credential exposure cannot be confirmed or ruled out without resolving executable behavior and the helper's callers. - **Evidence paths:** bin/reason.exe, .lpm-inspection-Cn1p7C/0-e60aabb8ee5f.txt, bin/native/win32/prebuilds/win32-arm64/win32-platform.node - **Review source:** ai\_review - **Reviewed:** 2026-10-20T01:44:20.150Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A helper gathers credentials from provider environment settings and local agent configuration. The available executable analysis does not show whether that helper is reached or whether the values are transmitted. - **Rationale:** The manifest has no lifecycle hook, and the agent-directory reference in the inspected runtime is used to construct local scan paths. However, bounded analysis of the CLI executable reveals credential-gathering code without resolving its reachability or destination, and the native addon is unsupported by the available analysis; this behavior remains unresolved. - **Files touched:** .codex/auth.json, opencode/auth.json ### Review decision - **Verdict:** Manual Review - **Confidence:** 86.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest identifies a Windows ARM64 native CLI package and contains no lifecycle hook., The sandbox runtime lists Claude command and agent directories as paths used during local scanning., The bounded executable analysis contains a helper that gathers provider credentials, but does not establish whether it runs or where those values are sent., The executable analysis warns that its source windows cannot establish loader reachability or rule out other native behavior; the platform addon could not be inspected as source. - **Evidence against:** The inspected sandbox code uses the agent-directory list to build local scan paths., The manifest contains package metadata and bundled files but no install-time script. ## Affected versions and remediation This report applies to @reason-machines/cli-win32-arm64@0.2.460. - Review the evidence and your use of @reason-machines/cli-win32-arm64@0.2.460 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
